CAS Announces New Series 3 DT85 Intelligent Data Logger

The Latest Version of the Popular dataTaker DT85 Has Arrived

CHESTERLAND OH—September 20, 2011

CAS DataLoggers has partnered with popular manufacturer dataTaker to announce the newly released Series 3 DT85 Intelligent Universal Input Data Logger, a smart data logger emphasizing flexibility, accuracy and durability. Able to connect to a large number of inputs simultaneously, the new Series 3 model offers users even more datalogging features combined with more precise measurements. These upgrades made to the successful Series 2 DT85s are inspired directly from the needs and comments from customers all over the world. Designed for use in a wide variety of applications and focusing on versatility across many different measurement types, the Series 3 DT85 logger offers users an impressive array of communications features which make it an ideal solution for real-time data acquisition, remote monitoring and control needs.

Improvements included with the dataTaler DT85 Series 3 include improved cold junction compensation using a high-precision RTD sensor accurate to 0.1%, enabling up to 5x more accurate thermocouple measurements. Single-ended 2-wire resistance measurements allowing 3 resistance measurements per input channel have also been added for use in monitoring sensor cable integrity. Additionally, a 5V terminal is now included to power external devices with a limit of 25mA, further increasing the DT85’s flexibility.

DT85 dataloggers are designed with size in mind, featuring 16 to 48 universal analog sensor channels and 12 digital channels, 4 high-speed counter inputs, phase encoder inputs, and programmable serial sensor channels. These allow connection to most sensors and data measurement sources so that almost any physical value can be scaled and logged including temperature, voltage, current, 4-20mA loops, resistance, strain gauges, frequency, and more. Measurements are made at an 18-bit resolution across a ±30 V input measurement range, and for more demanding applications, the dataTaker DT85 is expandable up to 900 analog inputs. The data logger can store up to 10 million data points in user-defined memory and features independent control of schedule size and mode to log only as long as needed. The DT85 also archives data on alarm event, copying to USB memory and transferring via FTP if needed, providing data directly to the office over the internet or mobile phone network without the need for polling or specific host software.

The Series 3 DT85 stand-alone, low power data loggers feature a built-in display and are renowned for their robust construction capable of withstanding extreme environments and made to last over years of constant use. Their powerful communications capabilities include RS232 with modem support, USB, Ethernet and USB memory stick ports enabling connection to the DT85 locally, remotely or over the Internet. Featuring support for multiple SDI-12 sensor networks, Modbus for SCADA systems, FTP and Web interface, and 12V regulated output to power sensors, the DT85 is ready for duty in environmental, industrial and many other types of monitoring projects.

User-friendly dEX software is included free with the Series 3 DT85, utilizing an intuitive graphical interface enabling users to quickly configure the data logger and view real-time sensor measurements, calculations and diagnostic information, all in a hassle-free Windows Explorer style interface. Users can also view their real-time data in mimics, trend charts, or tables, and retrieve historical data for analysis. To get users up and running, dEX comes built-in with no applications to install, runs directly from a web browser, and can be accessed either locally or remotely anywhere that a TCP/IP connection is available including worldwide over the Internet. Users can view dEX using any of the logger’s built-in communications ports including Ethernet, USB and RS-232.
